Architecture
Object Backend
LocalFS and S3-compatible object storage for file data.
File data lands on the object backend as blocks:
- LocalFS — blocks as files under a local directory; ideal for development and for inspecting the physical layout.
- S3-compatible — MinIO, RustFS, Ceph RGW, AWS S3, and other services; ideal for elastic, object-storage-backed infrastructure.
Agent-generated artifacts, logs, indexes, and checkpoints persist here. The object backend benchmark compares IO performance across backends.
